Surgery for adolescent hallux valgus.

Attention is directed to the large number of operations for the correction of hallux valgus in the adolescent and important variations among the most popular surgical procedures, as well as the factors influencing the outcome of these operations. A consistently reliable operation is the modified Wilson procedure, a metatarsal shaft osteotomy. Its merits are its technical simplicity, minimal damage to soft tissue, and pleasing correction of deformity. The operation narrows the forefoot, relaxes soft tissues, and maintains excellent mobility of the first metatarsophalangeal joint.

Preliminary results of the Sheehan total knee prosthesis.

A review of 50 knees in 42 patients operated upon between August, 1973 and November, 1976 is presented. Following initial good results, problems have been encountered with the passage of time. Complications due to design faults, selection, and technical pitfalls are analysed. Patients who have grossly unstable and deformed knees are not suitable for this type of prosthesis. The high density polyethylene central flange in the tibial component is not strong enough to withstand valgus or varus forces. Full correction of valgus, varus, or flexion deformities is essential if late complications are to be avoided. Associated external rotation deformities in grossly valgus knees have to be fully corrected to prevent late dislocation of the patella. Our conclusion is that at present there is a place for both the hinged and hingeless type of prosthesis in total knee replacement.

Racquet player's pisiform.

Four patients whose sport involved wielding a racquet presented with symptoms at the base of the hypothenar eminence which were due to minor degrees of subluxation of the pisiform. In two there was in addition a chondromalacia of the articular cartilage of the joint.

Chronic overuse injuries of the piso-triquetral joint in racquet game players.

Three squash racquets and one badminton player presented with pain in the base of the hypothenar eminence, due to minor degrees of subluxation of the pisiform bone. Two of them also showed chondromalacia of the articular cartilage of the pisotriquetral joint. All four patients were relieved by excision of the pisiform bone and had returned to their normal daily and sporting activities within three months of their operation.

Unstable dorsal fractrue-dislocation of the fifth carpometacarpal jont.

Four cases of unstable fracture-dislocation of the fifth carpometacarpal joint are reproted, including 3 isolated dorsal fracture-dislocation and 1 dorsal fracture-dislocation associated with a fracture of the fourth metacarpal bone. All cases required open reduction and Kirschner wire fixation which resulted in good function. Attention is drawn to the frequent delay in diagnosis. The applied anatomy is discussed.

Metatarsal osteotomy for metatarsalgia.

An oblique osteotomy in the distal half of the metatarsal shaft is described for the treatment of metatarsalgia due to prolapse of one or more of the middle three metatarsal heads. Thirty-eight patients who have had this operation have been followed up for a period of from two to five years. The operation is simple, recovery is rapid and symptoms have been well relieved.
